At age 5, Grossman started working at the family deli, Grossman's Cafeteria and Deli on 40th Street and Girard Avenue, a well-known restaurant of the 1930s through the '60s.
Grossman was just 25 years old when he experienced a life-threatening accident, where he was catapulted under his truck. He was not expected to live, and was told he would never walk again. At the time, he had a wife and 2-month-old baby. Grossman spent nine months in the hospital in a body cast, but walked out on his own. His recovery took another two years, and it prompted him to change careers and go into the insurance business.
He first worked for the National Life and Accident Company. For 10 years, he served as the leading agent out of 10,000. After that, Grossman created his own firm.
During his long career, he won about every award the insurance industry offered, as well as awards for outstanding community service. He was elected a charter member of the Phoenix Insurance Company Hall of Fame, and was one of 63 founding members of the International Million Dollar Forum — the forerunner of the Top of the Table for the Million Dollar Round Table, the most prestigious and highly regarded in the insurance industry.
For many years, Grossman was "Man of the Year in New Jersey," a state award for excellence and professionalism in the insurance industry, and received a Distinguished Service Award from the Quaker City Shrine Club. He was also a 32nd degree Mason.
Grossman also donated time and money to various charities and to helping others.
He is survived by daughters Gloria Grossman Shurman, Eileen Grossman Staller and Judy Grossman Norman; son Jack Grossman; eight grandchildren; and three great-grandchildren. He was predeceased in April 2006 by his wife of 65 years, Lois Grossman.
